To @ZZ whmm it 17m/y concern.'

Be it known that I, FREDALBERT OLOG- sToN, acitizen of the UnitedStates, residingat Bridger, in the county of-.Oarbonand'State of-Montana, haveinvented certaininew. and useful Improvements .in ATelegraph Out-Outs and I do hereby declare `the following to be a full, clear, and exactl description ofthe invention, such-aswillenable othersskilledin the art to which it appertainsvtofmake and use the same.=

My inventionrelates to .cut-outs for use in telegraph-ofliceswhere two or more Sounders are employed; andv its object is to provide means-whereby allof the Sounders within the office except the one being used can be simultaneously. cut out, so that theoperator will not be annoyed by the operation` of other instrumentsthanathe one manipulated by him.

Considerable annoyance and inconvenience has heretofore beenexperienced by operators because ofthe noise made by several sounders working whena message is being sent or received, and it has been customary to disconnect the Sounders or else stop their operationby placing'obstructions within them.

The object of the invention is, as heretofore stated, to provide means whereby all of the Sounders except. the Ione being used'may be cutout, so as-to obviate their noise, and whereby all of thesounders may be promptly placed in circuit wherever desired.

The invention consists of a casing having a plurality of levers each-of which is electrically connected to a sounder. All of the levers support and are normally in contact withza return-plate which is electrically connectedt to ay common return-wire, so that when the parts are in their normal positions the current will pass through all of the Sounders and through the levers` connected thereto and from thence to the return-plate and to the common return-wire, so thaty all of the sounders can be operated in unison. Each lever, however, has means whereby it can be raised independently of the others, and by raising any one of the levers the return-plate will be elevated therewith and off of the remaining levers, so that but the one lever will remain in circuit and the others be cut out.

The position of the keys may be determined in any suitable manner, preferably by the position assumed by its operative button.

The invention also consists of the further povlell features hereinafter more clearly set ort ' 5 of the return-wire.

In the accompanying' drawings If have shown the preferred'formiof my invention;

In said drawings, Figure -1 is aiplan view of my improvedY cut-out'f with i its cap removed; Fig. 2 is a'seotion online x,gF.ig. 1'. Fig..8 is a sectionon line y y, Fig. 1. Fig. .4- is-a view similari-to Fig. 3, but showing tli'epositions of the parts whenyallbut one of the jlevers are cut out; ofl circuit with thereturnplate; and Fig. 5 is a detail lview of one ofthe levers of the cut-out.

Referring `to the figures by. numeralsofref.- erence, 1 is the base ofthe cut-out, having walls 2 thereon, which constitute'thefcasing of the device, and securedluponithe base adjacent. one of the walls arebinding-posts,

which are adaptedtopbe connected bywires-41;

withsounders. (Notshowm)V Another'binding-post 5 is located uponthe base' andhas-aw common return-wire 6 extending fromit. Each binding-post 3 is electrically connected,

as by means ofk a plate 7 andscrews 8, with-ayoke 9, which is securedwithin. the-casing;

andembraces one end of a lever10, whichis pivoted tothe yoke. One of these levers isprovided for eachibinding-post 3 and thelevers are preferably arranged; parallel with eachother andextending to points adj acent; the front of the casing of the cut-out. lever has a spring-strip11l fastenedto fit1 and extending longitudinally thereof, and the.

springs of all the levers normally contact. with and support areturn-plate 12, which is pivoted to a rod 13, extending'from side to side of the casing and electrically connected, by means of a plate 14, withthe binding-post A spring 15-is secured to the casing and bearsy on the return-plate', so that the same will be pressed in contact. with all of the springs 11. A cross-barflis disposed within the casing above the front or free ends-of the levers 10 and return-plate 12, and journaled within'this bar andwithin the front of the casing is a series of cranks 17, one being provided for each lever 10 and being disposed above its lever. A rod 18 connects each lever and its crank, andeach .crank has a button 19 disposed on the front of the casing, whereby the crank may be readily rotated manually.

In using the cut-out attachment herein described the common return-wire 6 is connected to the negative poles of all the batteries, while the wires 4 are connected to the instruments and thence through relays y to the positive poles of the batteries. One wire Each 1 IOO IlO

4 eXtends to each instrument, and it will therefore be understood that as plate 12 normally contacts with the springs 11 of all the levers 10 the currents entering through the wires 4 will all pass through their respective levers 10 land springs 11 to the return-plate 12 and the common return-wire 6. All the instruments will therefore operate simultaneously. Should the operator desire to cut out all but one of the instruments, so that he would not be annoyed by their noise, he turns the button 19 ot the instrument which he desires to operate to the right, thereby rotating the crank 17 and elevating the lever and rod secured thereto, that end of' the rod secured to the crank being directed to the right and slightly beyond a vertical plane and into engagement with the pin 17, placed in the path of the crank, the weight of the parts carried by the rod serving to hold the crank against casual rotation in the opposite direction. This upward movement of the lever and its spring 11 will lift plate 12 ofl" of the springs 11 of the remaining levers, and therefore the circuits will be broken through all of the levers except the one which has been raised by the operator. When it is desired to return the parts to their initial positions, it is merely necessary to turn the button so as to swing the crank back from its supporting-pin 17, and as all the buttons are normally in the same relation horizontally the proper button to be turned to bring` the parts back to their original positions can be readily distinguished.

A cut-out such as herein described can readily be connected to telegraph-circuits, and it will be understood that the same may be used with any desired number of instruments, it only being necessary to employ one lever 10 for each sounder.

Having thus described my invention, what I claim as new, and desire to secure by Iletters Patent,'is-

1. In a cut-out of the character described, the combination with a series of pivoted devices each adapted to be electrically connected to a sounder; of a common return device movably mounted above and normally contacting with all of the pivoted devices, and means for actuating any one of said pivoted devices to raise the return device out of contact with the remaining pivoted devices.

2. In a cut-out of the character described, the combination with a series of ivoted devices each adapted to be electrical y connected to a sounder; of a spring-pressed, electrically-supported return device mounted above and normally contacting with all of the pivoted devices, and means l'or separately actuating any one of the pivoted devices to raise the return device out of contact with the remaining pivoted devices.

In a cut-out ol' the character described, the combination with a series oi levers, each adapted to be connected to a sounder; ol` a return device normally supported by and electrically connected to all of the levers, and means for separately actuating any one of the levers to remove the return device from electrical connection with the remaining levers.

4. In a cut-o ut of the character described, the combination with a series of levers adapted to be electrically connected to a series ol Sounders; of a spring-pressed return-plate movably mounted adjacent to and normally electrically connected with all of the levers, and means for separately actuating any one of the levers to break the electrical connection between the return-plate and the remaining levers.

5. A cut--out of the character described comprising a series of levers adapted to be electrically connected to a series of Sounders and springs mounted upon the levers, a spring-pressed return-plate adapted to be electrically connected to a common returnwire, said'plate normally contacting with all of the springs of the levers, and means for separately actuating any one of the levers to move the plate out ot contact with the springs of' the remaining levers.

6. A cut-ont of the character described comprising a series of levers adapted to be electrically connected to a series or' Sounders, and springs mounted upon the levers, a spring-pressed return-plate adapted to be electrically connected to a common returnwire, said plate normally contacting with all of the springs of the levers, cranks mounted within the casing, rods connecting each crank with one of the levers, and means for separately rotating the cranks to actuate any one oi the levers to move the plate out oi' contact with the springs of the remaining levers.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
